>>F<< SUCTION HOSE INSTALLATION

1. Align the oil reservoir side suction hose marking

(white) within the area shown and connect the
suction hose.

2. Align the oil pump side suction hose marking

(yellow) within the area shown and connect the
suction hose.

INSPECTION

M1372005800029

Power steering oil pressure sensor check

Refer to GROUP 13A, Troubleshooting

P.13A-20

NOTE: The engine-ECU <M/T> or the
engine-A/T-ECU <A/T> diagnoses the power
steering oil pressure sensor. If there is a problem,
diagnosis code is set.
